AT&T has begun rolling out Wireless Emergency Alerts updates for iPhone 4S and 5, so you won’t be the last folks to know if the entire northern hemisphere is about to be covered in ice à la Day After Tomorrow.

You’ll receive a notification from the carrier when your update is ready, but only if you’re using iOS 6.1 or higher.

Once installed, AMBER and Emergency alerts are automatically sent to your phone unless you switch them off via Settings. However, should you be tired of Obama, just know that there’s no way to switch off Presidential alerts.

So now Barack can track your calls and send you messages, too.Hat Tip Michael
